Debraj built an electrical dummy load to test his power supply and wrote a post on his site detailing it’s assembly:
Recently, I purchased a power supply that claimed a max current of 2A and 0~15V. So I wanted to test it. I had a 36 watts bulb (used in motor cycles), but that was too much. Then, I thought of the dummy load that is explained by Dave in his video blog.
My version is similar, but I changed certain components to my liking (and what ever was already available with me)

Hi,
Just wondering, how can I use the dummy load you created to test a negative power supply?
Thanks!
